INDRIYANTO, YOGI (2007) RANCANG BANGUN PINTU OTOMATIS DENGAN MENGGUNAKAN SENSOR PASSIVE INFRA RED KC7783R DAN MIKROKONTROLER AT89S51. Undergraduate thesis, Department of Physics, Diponegoro University.
The door with automatic system use microcontroller AT89S51 has been designed and realized. This instrument can be exploited as a door automatic system at bank or place requiring it. This system consisted of hardware and the software. The hardware consist of microcontroller AT89S51, PIR sensor KC7783R, relay, limit switch and motor gear. The microcontroller’s software was built on assembly language. This system work after PIR sensor KC7783R detected human being movement, hence PIR sensor KC7783R will send the singnal to mikrokontroler, mikrokontroler will fire the relay, after relay blaze hence relay will move the motor gear. This system have realized and can move a door with automatic. The door movement is open/close the door motion. Although, this system has a weaknes, it is when the door still in closing process, if the sensor detect a human movement, it will open as soon as possible, but this condition is only working at the beginning of system activation. After a several moment, this condition doesn’t work anymore.
